Abstract

Klemmvorrichtung zum Einsetzen in einen Klemmkanal eines Zylinders (1) einer Rotationsdruckmaschine, die Klemmvorrichtung umfassend ein Klemmstück (12) mit einer Klemmfläche (19), das um eine Schwenkachse (13), die in Bezug auf den Klemmkanal etwa ortsfest ist, schwenkbar gelagert ist, wobei das Klemmstück (12) gegen eine im Klemmkanal gebildete Gegenklemmfläche schwenkbar ist, und wobei das Klemmstück (12) so dimensioniert ist, dass eine Zentrifugalkraft des drehenden Zylinders (1) in einem Klemmspalt zwischen der Klemmfläche (19) und der Gegenklemmfläche eine Klemmkraft erzeugt, wobei die Klemmkraft mit zunehmender Drehgeschwindigkeit des Zylinders (1) zunimmt.

Figure imgaf001
Clamping device for insertion into a clamping channel of a cylinder (1) of a rotary printing machine, the clamping device comprising a clamping piece (12) with a clamping surface (19) which is pivotally mounted about a pivot axis (13) which is approximately fixed with respect to the clamping channel wherein the clamping piece (12) is pivotable against a counter-clamping surface formed in the clamping channel, and wherein the clamping piece (12) is dimensioned so that a centrifugal force of the rotating cylinder (1) in a nip between the clamping surface (19) and the counter clamping surface a clamping force generated, wherein the clamping force increases with increasing rotational speed of the cylinder (1).
